Regrettably, the situation isn't really that new. Back in my teaching days, when I asked a young person why they'd not been in school the day before I'd often get the answer "I had to do the shopping for my mum". Initially I'd just protest that school finished at 3pm and the shops didn't close until 5.30pm, so that should have left plenty of time for shopping. However I began to learn from social workers that "Doing the shopping" was just a code that youngsters used to mean "Helping my mum bathe herself and go to the toilet, doing all the cooking, the cleaning and shopping, looking after my pre-school siblings, etc, etc".
Lots of people tried to improve things for such youngsters but their efforts often seemed not to yield much fruit. (I was teaching at secondary level but I found out that some of those youngsters had been doing all those caring tasks from the ages of just 7 or 8).
